How to define rule for JSON body Mockoon

I have a simple GET method in Postman:

{
    "requestId": 200
}

For simplicity I wanted to return 200 response on requestId 200 and 400 on requestId 400 and I'm not able to do that in Mockoon 6.1.0.

I have 2 responses for one route with a rules

Body $.requestId equals 400

(value 200/400 is different if rule for first request and for second)

Rules from JSON file:

{
          "rules": [
            {
              "target": "body",
              "modifier": "$.requestId",
              "value": "200",
              "invert": false,
              "operator": "equals"
            }
          ],

          "rules": [
            {
              "target": "body",
              "modifier": "$.requestId",
              "value": "400",
              "invert": false,
              "operator": "equals"
            }
          ],

}

I always get response 200.

Solution

  • I think this is due to the fact that your requestId field is a number. It appears the "equals" rule plays well with strings but not numbers.

    As a workaround you can select "regex" in the comparator list.
